This is some good info, but it's important to note this quote: "We assumed that we would observe a 30 percent recurrence rate among the placebo group. It is possible that the placebo juice inadvertently contained the active ingredients that reduce urinary tract infection risk, since both juices contained Vitamin C" "Another possibility is that the study protocol kept participants better hydrated, leading them to urinate more frequently, therefore decreasing bacterial growth and reducing urinary tract infection symptoms" Staying hydrated is one of the most important things to avoiding a UTI in the first place. Perhaps more studies should be done before we discredit it. Plus, cranberry is only now being tested correctly for quality. Here's some more info on BL-DMAC: http://www.myellura.com
